BACKGROUND

With the emergence of smart phones in recent years, the demand forminiature camera lens is increasing day by day, but in general thephotosensitive devices of camera lens are nothing more than a chargecoupled device (CCD) or a complementary metal-oxide semiconductor sensor(CMOS sensor), and as the progress of the semiconductor manufacturingtechnology makes the pixel size of the photosensitive devices becomesmaller, plus the current development trend of electronic productstowards better functions and thinner and smaller dimensions, miniaturecamera lens with good imaging quality therefore have become a mainstreamin the market.

In order to obtain better imaging quality, the lens that istraditionally equipped in mobile phone cameras adopts a structure of athree-piece, four-piece, or even five-piece, or six-piece lens. Also,with the development of technology and the increase of the diversedemands of users, and as the pixel area of photosensitive devices isbecoming smaller and smaller and the requirement of the system on theimaging quality is improving constantly, a nine-piece lens structuregradually appears in lens designs. The present nine-piece lens structuregenerally has good optical performance, however an optical focal length,lens spacing, a lens shape thereof are still arranged unreasonably, sothat the nine-piece lens structure cannot meet a design requirements ofa large aperture, ultra-thin and wide-angle in the case when the lensstructure remains good optical characteristics.
